“Most likely Shaq, to be honest,” Celtics coach Doc Rivers said following Monday’s practice. “We haven’t officially announced it but most likely.”

Rivers added that back-up centers Jermaine O’Neal and Semih Erden will both suit up and be ready to play. O’Neal has been playing with torn cartilage in his left wrist while Erden has a sore shoulder that Rivers indicated will take some “managing” to keep him healthy enough to play.
